Please i need some help...
I'm using OC and i've followed the guide on page 1, however it would seem that i having a few issues.
It would seem that i'm not getting any acceleration with my RX580 and my HDMI ports are not working. I thought i had it figured out, however i was mistaken.

I'm running Catalina

EFI folder attached
Any assistance would be greatly appreciated.

EDIT: I'm now getting acceleration using iMacPro1,1 however still no dice with the HDMI.

EDIT 2: so It HDMI now seems to be working after i removed agdpmod=pikera

@mattystonnie , if you wouldn't mind going through my EFI folder and advise if there are any optimisations which i could do. Asking you as you seem to be the authority in this area :)

Hello everyone, I'm desperate and I need help ...
Clover, Catalina 10.15.7 with Asus Arez Vega56 works good...but if you turn off / turn on the monitor, the cursor and windows start to stutter. if you pull out and insert HDMI, it also starts to stutter ... only reboot solves the problem

I also have an Nvidea GT710 and the system works perfectly! ...

I've been trying for a month to find the reason and all without results ...
ps: There was no such problem on MOJAVE system with Vega56 ...

I will be VERY grateful for any help ...

P.P.S - i tried RX5600xt on my system but with CLOVER i got reboot. With OPENCORE and agdpmod = pikera I was able to start RX5600xt, but I also have cursor micro lags...

Do you guys know what do I need to do to make hdmi audio work? I already have the latest version of WhateverGreen in the efi folder, in the hackintool application it appears like this in the screenshot I sent, in the sound settings the hdmi audio output appears, but I can't increase or decrease the volume and it doesn't come out sound on the loud speaker of the tv that is connected to the pc, has any boot-arg that needs adc in the config.plist or has to inject something somewhere else? I tried to use a kext that I found researching about it called hdmiaudio.kext but without success, and I don't have speakers to use on the motherboard's sound output

My videocard is an RX 5500xt 4GB from Gigabyte

Thanks for the very interesting work... I just tried out the SSDT for RX580, and got the following results (before and after sleep)...

Before SSDT:

OpenCL:

After SSDT:

So overall, a very mediocre increase in performance... but GPU die temp has come down anywhere from 5c to 10c, which is a real achievement!

Hope someone finds this info useful. PS. Using iMacPro1,1 SMBIOS without agdpmod=pikera, Sapphire Pulse RX 580 8GB

Anyone else's RX5700 XT does a load buzzing noise when moving the mouse/scrolling on pages? Like a very load coil whine?
I saw a lot of reports of this using Windows, but after drivers updates from like 6 months ago there are not a lot of reports.
This happens to me but only on my MacOS boot (I guess because of outdated drivers?). When I restart and boot into Windows it doesn't happen on windows. Only on MacOS.

Any fix for this?
I have this with Sapphire Nitro+ RX5500XT. It's annoying as hell in a quiet room and I hear it in both Windows 10 and macOS Catalina.

Thank you for your wonderful guide.
It worked with "HP8300CMT RX570 Opencore 0.6.3 Catalina 10.15.7" with "PEGP to PGP0" setting.

I may have done something wrong, but I cannot get the Orinoco framebuffer for my RX580. Using OC 0.6.3 on Big Sur, I install the RX580 SSDT and AGPM.kext, adding them to the config.plist but it still shows RadeonFrameBuffer.

Any help would be appreciated.

edit: FWIW, I have a MSI 8GB RX580 card with 2 x HDMI, 2 x DP, 1 x DVI

edit #2: I removed the SSDT and instead used the DeviceProperties detail from https://www.tonymacx86.com/threads/amd-radeon-performance-enhanced-ssdt.296555/post-2118592

This enabled the orinoco framebuffer. Success! Except, it doesn't solve the problem I hoped it would address.

System and Samsung 4K HDR TV boot fine. But if I turn off the TV and turn it on again, there is no signal. Have to reboot the hackintosh every time.

Anyone know what that is caused by?

I have updated my attached files.

Some before and after geekbench scores. Running an ASRock RX 5500 XT. Not too bad, especially on the OpenCL score!
